中文摘要: 以核桃乳为主要原料,采用乳酸菌干粉制剂 HS101 通过发酵工艺的研究开发发酵型核桃乳饮料。试验结果表 明:最适宜的辅料配比为 3 %乳清粉,4 %葡萄糖;杀菌温度 88 ℃。最佳发酵条件为 pH 7.0,接种量 0.014 g/250 mL,培养 时间 8.0 h,培养温度 42 ℃。发酵型核桃乳的 13 种氨基酸均有不同程度的提高,其中赖氨酸含量增加了 0.19 %、色氨酸 含量增加了 0.03 %。由此可见,经过乳酸菌发酵,提高了核桃乳的营养价值。
Abstract:The fermentation process of walnut milk by lactic acid bacteria HS101 was studied .The results showed the most suitable materials ratio was: 3 % whey powder, 4 % glucose, best sterilization temperature was
88 ℃. The optimum conditions were pH 7.0, inoculum 0.014 g / 250 mL, cultivation time 8.0 h and temperature 42 ℃. 13 kinds of amino acid increased at different degrees in fermented walnut milk, in which lysine increased 0.19 % , tryptophan 0.03 %. According to the above result there was a significantly improvement in the nutri- tional value of walnuts milk after the fermentation.
